One of the most important applications of De Moivre's theorem is to find the q t h roots of a complex number. Let z = x + iy be a complex number. Let z = r {cos q + i sin q } be its polar form. And z 1/q be the q th root of z. T..
Argand diagram of the qth roots of a Complex number
All the q-th roots of z lie on a circle centred at the origin O and having radius equal to the real, positive q t h root of r. One of them has amplitude q /q and others are uniformly spaced around the circle separated from others by an angle 2p ..

Tutor was excellent, asnwered the question rapidly and provided the information I needed to understand the problem.
Very fast and clear. Made sure I understood the concepts instead of giving the answers to the problem.
Terific helped showed how to apply formulas i will study these examples to go further--much gratitude--will come back again ThankYou
Tutor Vista tutors actually helped me to think through some of the problems instead of just doing them for me.Now i am more confident with math ,Thank you all
Looking for More Help!
